Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while inspecting.

2. Inspect and Repair Fluid Leaks

Tools Required: Rags, leak detection dye (if necessary)
Check for oil leaks by cleaning the engine and monitoring for fresh oil spots.
If oil is leaking, replace the oil filter and tighten any loose oil pan bolts.
Inspect the transmission cooler lines for leaks; replace any damaged lines.

3. Replace Burnt Fluids

Tools Required: Fluid pump, funnel, appropriate fluid containers
If engine oil is burnt or low, drain the old oil and replace it with manufacturer-recommended engine oil.
Similarly, if the transmission fluid is burnt, drain and replace it with new transmission fluid, ensuring to follow the proper service procedure.

4. Brake Inspection and Replacement

Tools Required: Jack, jack stands, lug wrench, brake cleaner
Safely lift the vehicle and remove the wheels to access the brake components.
Inspect brake pads for excessive wear or overheating; replace if necessary.
Check the rotors for warping or damage; resurface or replace as needed.

5. Final Assembly and Clean Up

Reinstall any removed components, ensuring all bolts are tightened to specifications.
Reconnect the battery and start the engine, allowing it to reach operating temperature.
Monitor for any unusual smells or leaks during this process.
